Here is the manual workaround discussion from an earlier post of mine. It takes less than a minute a day once you get used to doing it.

Now that I have been mucking around in MFP for a bit, I realize that they have their own version of adulterated BMR. At least they don't call it BMR like Garmin does. MFP calls it "Calories Burned From Normal Daily Activity". My number (with normal daily activities setting on Sedentary) is 1,900 which is 70 calories higher than my Garminized BMR of 1,830 and 25% higher than my "Real" BMR of 1525. What this means is that MFP, like Garmin, has baked some level of activity into their baseline number.

To make manual integration work out right, you would add your Garmin Total Calories less your MFP "Calories Burned From Normal Daily Activity" (CBFNDA) in the form of a Vivifit Custom Exercise in order to feed MFP an accurate picture of TDEE (Total Daily Energy Expenditure or BMR+Activity Based Calorie Burn).

For example, Garmin Connect Modern (GCM) says I burned 4,254 total calories yesterday (1,830 BMR + 2,424 Active). Subtracting MFP's 1,900 CBFNDA from 4,254 leaves 2,354 which is the number of calories I put in as a custom exercise. Works perfectly.

I wish I had all of the time back I have spent whining at Polar and Garmin about their failure to integrate with MFP. I still wish it was automatic but, for now, I trust this more than anything Garmin might decide to feed MFP on their own. The main problem with this work-around is that you don't get accurate real-time feedback regarding your status at any point "Today" as GCM does not give you an accurate total calorie burn until you sync after midnight yesterday so this is necessarily a "morning after" retrospective exercise.

To summarize, sometime TODAY

1. Get YESTERDAY's Total Calories From the Steps widget on your GCM Health & Fitness (default) dashboard
2. Subtract your MFP Calories Burned from Normal Daily Activities (found under Goals in the Your Diet Profile section)
3. Add the difference to MFP as a custom exercise (I call mine Vivofit Activity but call it anything you want)

All done. How easy is that?

Update. I still cannot guarantee anything but I can say that Garmin is well aware of its Vivofit Users' demand for MyFitnessPal integration. I can also say that Garmin is not investing any effort in developing a calorie consumption capability of their own.

As a side note, this new steps thing on MFP is, maybe, a little better than absolutely nothing in the way of activity monitoring but not much. It's given be a 113 calorie adjustment for 5,512 steps at 3:30 PM (Vivo number 7,462 steps) including a 5K run.

"If you’re lucky enough to have an iPhone 5S, we’ve got an extra treat just for you: Using the M7 co-processor found in the 5S, you can now automatically track your steps simply by using you iPhone 5S—no external apps or devices necessary. However, if you have an activity tracker that you already enjoy using, you can choose exactly how you want to track your steps. Two things iPhone 5S users should know: - See more at: http://blog.myfitnesspal.com/2014/05/now-you-can-track-your-steps-in-myfitnesspal/#sthash.MThzmZvS.dpuf"

It's pretty lame.

My MFP Calories Burned From Normal Daily Activity= 1,900 cal/day

My Garmin Baseline = 1,848

My BMR from MFP's own online calculator found here: http://www.myfitnesspal.com/tools/bmr-calculator 1,520.

So it looks like Garmin is baking in an extra 20% (which is what they have told me) and MFP is baking in an extra 25%.

I am philosophically against baking in any level of activity. We have a 24/7 activity tracker. Let it MEASURE our activity and then add in an appropriate calorie burn for it.

Garmin admits that the Vivofit's accelerometer measures all activity. In a kind of stupid move, Garmin focused first on eliminating the counting of false steps. Having achieved that, they began awarding extra calories only for steps (or HR) and ignored the rest of the data replacing it instead with this arbitrary 20% BMR "mark-up". Too bad they made that choice when they had the tools to do something more elegant but equating precision with calorie expenditure estimates is a fools errand anyway.

So the trick here is simply to make sure to exceed MFP's Calories Burned From Normal Daily Activity every day and to record that positive difference as exercise.

I do expect Garmin to be integrating soon but they have some internal messes to clean up first. Patience is a virtue .

You are right. Lets start over.

Please go to : http://www.myfitnesspal.com/tools/bmr-calculator. Plug in your numbers and tell me what you get for BMR.

Next, go into settings on both MFP and Garmin Connect and make sure they have the same values for height, weight, sex, and age.

Let me know when you have done that and we will go to the next step.

Yes marcellinus21 that seems too high.

On MFP, please go MY HOME/Settings/Update diet/fitness profile and tell me which radio button is "pressed" here:

How would you describe your normal daily activities?
Sedentary: Spend most of the day sitting (e.g. bank teller, desk job)
Lightly Active: Spend a good part of the day on your feet (e.g. teacher, salesman)
Active: Spend a good part of the day doing some physical activity (e.g. waitress, mailman)
Very Active: Spend most of the day doing heavy physical activity (e.g. bike messenger, carpenter)

For people like you with activity trackers, I would always recommend the lowest upwatd adjustment possible. In this case that is Sedentary.

Please try that and let us all know what happened.
